Hidden Perils: Four Unseen Threats Lurking within QR Codes
In today's digital world, Quick Response (QR) codes have become an increasingly common feature in our daily lives. From yogurt containers to museum exhibits, these scannable codes offer a convenient way to access information, make payments, and even donate to charity. However, as with any technology, there are potential risks associated with QR codes, particularly when it comes to cybersecurity.
Cybercriminals have developed a variety of QR-based schemes, exploiting the technology's widespread use to target unsuspecting users. These schemes can direct users to fraudulent websites designed to steal personal or financial information, automatically connect users to Wi-Fi networks controlled by attackers, or prompt the download of malicious applications that compromise the security of the user's device.
To avoid potential cyber threats and attacks, several safety precautions are essential when scanning QR codes. First and foremost, users should scan only QR codes from trusted sources. This means avoiding random or unsolicited codes, especially those found in public places or received unexpectedly in emails or messages.
When scanning a QR code, it's also important to use your phone’s built-in camera app for scanning. Most modern smartphones have integrated QR code scanning features that require minimal permissions, reducing privacy risks. Avoid third-party scanner apps unless they are highly reputable and limit permissions to only camera access.
Before opening a link or website accessed through a QR code, users should preview the URL or link. Use QR code scanners that display the target URL before opening it so you can check for suspicious or unrelated domains. Never proceed if the URL looks dubious or lacks HTTPS with a valid SSL certificate.
Users should also be cautious about where the QR code directs them. Never enter sensitive information such as passwords, credit card details, or personal data on websites accessed through QR codes unless you are absolutely sure about the site’s legitimacy. Look for secure connections (HTTPS) and confirm the domain matches the expected official website.
Other safety precautions include avoiding QR codes prompting app downloads or excessive permissions, beware of urgent or threatening messages linked to QR codes, keeping your device software updated, disabling automatic link opening in QR scanner apps, and reporting suspicious QR codes.
Seifallah Jedidi, Head of Consumer Channel for META at Kaspersky, emphasises the importance of using QR codes safely and responsibly. "QR codes have already become an integral part of our daily lives," he states. "It is essential for users to know how to use them safely and responsibly."
By following these precautions—trusting sources, verifying URLs, using secure scanning methods, and maintaining device security—users can significantly reduce the risks associated with scanning QR codes and protect themselves from cyber threats.
